Stepper Motor Driver DQ542MA

DQ542MA is a type of two-phase hybrid stepping motor driver, the
drive voltage of it is from 18VDC to 50VDC. It is designed for use
with 2-phase hybrid stepper motor of all kinds with 42mm to 86mm
outside diameter and less than 4.0A phase current. This circuit
that it adopts is smiliar to the circuit of servo control which
enables the motor run smoothly almost without noise and vibration.
Holding torque when DQ542MA run under high speed is also
significantly higher than the other two-phase driver, what’s more,
the positioning accuracy is also higher. It is widely used in
middle and big size numerical control devices such as curving
machine, CNC machine, and computer embroider machine, packing
machines and so on.
